PRAGUE, July 24 (Xinhua) -- Czech and Polish presidents Vaclav Klaus and Lech Kaczynski Wednesday agreed that Ireland, which recently rejected the Lisbon treaty in a referendum, now plays a crucial role in the treaty's future.

    Klaus said he had not changed his negative stance on the EU reform treaty.

    "For me there is no point in further discussing it without a change in the Irish result," said Klaus after one-hour talks with his Polish counterpart in Lany chateau, the Czech presidential summer residence.

    "The key lies in a change in Ireland's position. Without Ireland the treaty does not exist. However, Poland will not be an obstacle to its ratification," said Kaczynski, adding he is an optimist about the matter.

    Klaus pointed out he considers the Lisbon treaty "a mistake, a fault bad for Europe."

    The Lisbon treaty must be ratified by all 27 EU member states to take effect. Twenty-three countries' parliaments, including Polish, have already ratified it.

    The European leaders agreed at a summit in Brussels in June that the treaty's ratification would continue regardless of the Irish "No."

    The Czech Republic, one of the EU countries not to have ratified the reform treaty yet, pushed through at the summit a clause, saying that the ratification process in the country would be suspended until the Constitutional Court assesses the treaty's compatibility with Czech law.

    The Polish and Czech presidents supported the integration of Georgia and Ukraine into NATO, at their meeting at the Czech presidential chateau in Lany today.
